The runaway popularity of personal electronic devices has led to a huge global demand for compact yet powerful rechargeable batteries. Since hitting the market in the 1990s, lithium-ion technology has taken the lead in meeting this need.
But concerns over the relative scarcity of lithium and the toxicity of other common lithium-ion battery ingredients such as cobalt are driving the search for an alternative. Sodium, around 1000 times more abundant than lithium, could be the answer.
A fundamental component of protein, nitrogen is the most common pure element on Earth, making up nearly 80 percent of our atmosphere. Yet despite its abundance, atmospheric nitrogen cannot enter the food chain without first being converted into a form that can be used by plants.
McGill University chemistry professor Matthew Harrington is aiming to develop a renewable alternative to petrochemical plastics by mimicking the astonishing chemistry of the velvet worm – a creature that has made a name for itself through its projectile slime.
Inhabiting the forest floors of Australia and South America, velvet worms catch their prey by shooting out a jet of liquid that rapidly thickens to a sticky gel before hardening into polymer fibres comparable in stiffness to nylon.

Cellulose, one of the three major components of plants, is showing great promise as a renewable source for many convenience products. It is made of glucose, a molecule which can be fermented by microorganisms into virtually any desired small molecule of interest. More especially it can be converted to ethanol to make sustainable biofuels.
The way individual atoms and molecules move in materials has important consequences on properties such as electrical conductivity, heat capacity and acoustics. Even in solids, atoms are always moving back and forth about some average position, and this motion occurs through specific wave-like modes called phonons. Phonons form elementary excitations in the material and can therefore carry energy in the form of heat. As temperature increases, so do the number of phonons and vice-versa. The group of Dr.
Do you have great shots of McGill campus-life? We're looking for new photos to feature on the Office 365 portal login page.
The Office 365 portal (https://portal.office.com)

McGill University researchers have discovered the consequence of adding titanium and other stabilizing agents to high performing stainless steel on the material’s localized corrosion mechanism.
In a study published in npj Materials Degradation, the researchers describe a suite of electrochemical techniques used to characterize the material’s corrosion properties both on the macro and micro scale.
The first edition of the ChemPhoto: McGill Department of Chemistry Photo Exhibition took place in February and March 2018. The winners were selected by popular vote (total votes: 266) and are:
- 1st place: Le Jaune et le Bleu by Chenghao Liu, Ehsan Hamzehpoor
- 2nd place: Painter Palette by Mahdi Roohnikan
- 3rd place: Holy smokes Batman, is this Kryptonite!? by Igor Huskić
The award ceremony took place during the bagel hour on March 29th.
Two Kavli Lectures are held at every ACS national meeting as the result of collaboration between ACS and The Kavli Foundation, an internationally recognized philanthropic organization known for its support of basic scientific innovation in astrophysics, nanoscience, neuroscience, and theoretical physics.
The Royal Society of Chemistry Twitter Poster Conferences are the biggest chemistry conferences ever organized as they are held entirely over Twitter. Chemists are invited to join this online conference by tweeting they poster, allowing people all over the word to share they research and engage with the scientific research community, without having to travel!
Researchers at McGill University have invented a new technique for measuring how quickly drugs interact with their molecular targets. The discovery provides scientists with a new way to investigate the effectiveness of drug candidates that might otherwise have been overlooked.
The new method centres on the principle of enzyme inhibition. Countless pharmaceuticals, ranging from antibiotics to chemotherapy drugs, work by blocking the action of enzymes, and the search for new enzyme-inhibiting substances remains a major focus of drug development.
